Answer:
c = 3.5 - x
Step-by-step explanati
x^2 - 14x + c = (x - 7)^2
x^2 - 14x + c = x^2 - 7^2
x^2 - 14x + c - x^2 = x^2 - 49 - x^2
-14x + c = 49
-14x / -14 + c = 49 / -14
x + c = 3.5
x - x + c = 3.5 - x
c = 3.5 - x

Answer:
Girls = 390
Step-by-step explanation:
Set up a proportion:
In a sample of 3:2, you have 5 kids in all.
So the the ratio of girls to kids in a sample of 5 is 2:5.
So set up a proportion:
(3/5) = (x/650)
5x = 650(3)
5x = 1950
x = 390
Answer:
390Step-by-step explanation:
Let number of boys be b and girls be g. Then we have:
g/b = 3/2g + b = 650From the first equation b is:
b = 2g/3Substitute b in the second equation
g + 2g/3 = 6505g/3 = 650g = 650*3/5g = 390What is the remainder when a^3 - 4 is divided by a+2?
a)0
b)-6
c)-2
d)-12
Answer:
The remainder is -12. Choice d)
Step-by-step explanation:
The Remainder Theorem
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial
[tex]P(a)= a^3 - 4[/tex]
To evaluate the remainder when P is divided by a+2, we only have to find P(-2):
[tex]P(-2)= (-2)^3 - 4[/tex]
[tex]P(-2)= -8 - 4=-12[/tex]
The remainder is -12. Choice d)

Describe the similarities and differences between your two circles. 3. Describe the relationship between the circumferences of the two circles. 4. Describe the circumference-to-diameter ratio of all circles.
Answer:
1. a. Please find attached, the diagram for the first circle with radius = 3 cm
b. Please find attached, the diagram for the second circle with diameter = 3 cm
2. The similarities are;
a) Both circles can be described by a point and a radius or a diameter
The differences are;
a) The length of the radiuses are different for the two circles (3 cm and 1.5 cm)
b) The circumferences of the two circles are different
c) The area covered by the two circles are different
3. The circumference of the circle with radius equal to 3 cm is larger than the circumference of the circle with diameter equal to 3 cm
4. The circumference to diameter ratio of the circle with radius = 3 cm is π
The circumference to diameter ratio of the circle with diameter = 3 cm is π
Both circles have equal circumference to diameter ratio given that the circumference = π × The diameter
Step-by-step explanation:
1. a. The radius length of the first circle = 3 cm
The diagram for the first circle with radius 3 cm is attached
b. The diameter length of the second circle = 3 cm
The diagram for the second circle with diameter 3 cm is attached
2. The similarities are;
a) Both circles can be described by a point and a radius or a diameter
The differences are;
a) The length of the radiuses are different for the two circles (3 cm and 1.5 cm)
b) The circumferences of the two circles are different
c) The area covered by the two circles are different
3. The circumference of the circle with radius equal to 3 cm is 2 × π × 3 = 6·π cm
The circumference of the circle with diameter equal to 3 cm is π × 3 = 3·π cm
Therefore, the circumference of the circle with radius equal to 3 cm is larger than the circumference of the circle with diameter equal to 3 cm
4. The circumference to diameter ratio of the circle with radius = 3 cm is 6·π cm/(2 × 3 cm) = π
The circumference to diameter ratio of the circle with diameter = 3 cm is 3·π cm/(3 cm) = π.
Both circles have equal circumference to diameter ratio given that the circumference = π × The diameter.

How do you solve 2(x-6)=x-14
Answer:
x = -2
Step-by-step explanation:
[2(x-6) = x - 14]
Multiply 2 by x and (-6) in parenthesis, distribution
[2x -12 = x - 14]
Add 12 to both sides
[2x = x - 2]
Subtract x from both sides
[x = -2]

M is the midpoint of PQ.
PM = 5x + 8 and PQ = 76, find x.
(2 Points)
Enter your answer
Answer: x=6
Step-by-step explanation:
Just think about how the problem is half
The value of x is 6.
Here,
M is the midpoint of PQ.
PM = 5 x + 6
PQ = 76
What is midpoint of line?
The midpoint is the middle point of a line segment. It is equidistant from both end points.
Now,
M is the midpoint of PQ.
Hence, PM = MQ
And, PQ = PM + MQ
⇒ PQ = 2 PM
⇒ 76 = 2 (5x + 8)
⇒ 38 = 5x + 8
⇒ 5x = 30
⇒ x = 6
Hence , The value of x is 6.

an exponential function is graphed on the grid
based on the graph, which statement about the function is true
a) the domain is the set of all real numbers
b) the domain is the set of all real numbers less than 3
c) the range is the set of all real numbers greater than or equal to 0
d) the range is the set of all real numbers greater than or equal to -9
Answer:
a) the domain is the set of all real numbers
Step-by-step explanation:
Given:
An exponential function and its graph.
A line parallel to [tex]x[/tex] axis is drawn at [tex]y=-9[/tex] which is a dashed line.
Dashed line means, the function does not attain a value equal to [tex]y=-9[/tex].
Domain of a function, [tex]y=f(x)[/tex] is the set of values which can be possible for the variable [tex]x[/tex] that can be given as input.
Range of a function, [tex]y=f(x)[/tex] is the set of possible values of [tex]y[/tex] i.e. the output of the function.
As seen from the graph, the domain of the exponential function does not have any constraint on it.
Therefore, any real number can be given as input.
So, a) The domain is the set of all real numbers.
Let us discuss about the range of function.
As stated above as well, the range of the function can not contain the value [tex]y=-9[/tex].
And there is no value possible below it.
So, the range is all real numbers greater than -9.
The answer is:
"a) the domain is the set of all real numbers" is true.
1) Point P has the coordinates (5,7) what is the image of P' after a 90-degree Rotation? 2) Point P has the coordinates (5,7) what is the image of P' after a 180-degree Rotation? 3) Point P has the coordinates (5,7) what is the image of P' after a 270-degree Rotation? 4) Point A has the coordinates (-5,7) what is the image of A' after a 90-degree Rotation? 5) Point Q has the coordinates (5,7) what is the image of Q' after a 270-degree Rotation? 6) L' (6,-7) is the image of L after a 180 rotation what are the original coordinates L 7) The point A (-5,-8) is first translated 6 units to the right and two units down to get A'.A' is then reflected in the y=-x line to get A''.A'' is then rotated counterclockwise around the origin 270 degrees to get A'''.What are the coordinates of A'''?
Answer:
1) The coordinates of P' is (7, -5)
2) The coordinates of P' is (-5, -7)
3) The coordinates of P' is (-7, 5)
4) The coordinates of A' is (7, 5);
5) Q' is (-7, 5)
6) The coordinates of L is (-6, 7)
7) The coordinates of A''' is (1, 10)
Step-by-step explanation:
1) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)
Therefore, given that the preimage P is (5, 7), we have the image, P', after 90 degrees clockwise rotation is (7, -5);
2) The coordinates of a preimage (x, y) after 180-degrees clockwise rotation gives the image (-x, -y)
Given that the preimage, point P, has coordinates (5, 7) the image, P', after 180-degrees rotation becomes (-5, -7)
3) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)
∴ The coordinates of the preimage, P = (5, 7), after 270-degrees clockwise rotation gives the image, P', = (-7, 5)
4) The coordinates of a preimage (x, y) after 90-degrees clockwise rotation gives the image (y, -x)
Therefore, given that the preimage A is (-5, 7), we have the image, A', after 90 degrees clockwise rotation is (7, 5);
5) The coordinate of the preimage, point Q is (5, 7) after 270-degrees clockwise rotation gives the image, Q', = (-7, 5)
6) The image of a preimage, (x, y) after 180-degrees rotation is (-x, -y). Therefore, given that the image of the preimage L, after 180 degrees rotation is L' (6, -7), we have the coordinates of L is (-6, 7)
7) The coordinates of the preimage, A = (-5, -8)
a) A is translated 6 units to the right and 2 units to give;
A'(-5 + 6, -8 - 2) = A'*1, -10)
b) (x, y) is reflected across the line y = -x, to give (-y, -x)
∴ A'(1, -10) is reflected across the line y = -x, A''(10, -1)
c) The coordinates of a preimage (x, y) after 270-degrees clockwise rotation gives the image (-y, x)
∴ The coordinates of the preimage, A''(10, -1), after 270-degrees clockwise rotation gives the image, A'''(1, 10).

1. A movie theater sells tickets for $9.00 each. Senior citizens receive a discount of $3.00. One evening the theater
sold 636 tickets and took in $4974 in revenue. How many tickets were sold to senior citizens?
Answer:
250
Step-by-step explanation:
x is adult tix, y is senior tix
9x + 6y = $4974
x+y= 636
x=636-y
9(636-y) +6y = 4974
5724 - 9y + 6y = 4974
-3y = 4974-5724
-3y=-750
